Abstract
Organic agriculture is a holistic system of agricultural production and integrated, which optimize health and productivity of agro-ecosystems in nature. Experiment for crop rotation consisted of three planting seasons done at Bener Village, Ngrampal District, Sragen Regency, began in June 2005 until July 2006. The treatment of field experiment in 1st planting season was using single factor arranged in Randomized Complete Block Design, repeated three times. This experiment consisted of 3 treatments, i.e. rice, soybean and groundnut. The experiment in 2nd planting season was continued to 3rd planting season using Split Plot treatment, and three replications. Main plot was residual from legumes/paddy in the first experiment with three treatments: straw, peanuts and soybean. Sub plot was combining organic+NPK fertilizer with the seventh treatments: Organic fertilizer and recommended rate NPK, Organic fertilizer and optimum rate NPK, Organic fertilizer and farmer rate NPK, recommended rate NPK, optimum rate NPK, farmer rate NPK, with no fertilizer. The result of the experiment showed that the role of legume can substitute rice plant on rice-rice-rice crop rotation. Groundnut-rice-rice and soybean-rice-rice rotations had N-total significantly higher and P-avalaible significantly not different, however content of organic matter, and K-exchange were significantly lower compared to on rice-rice-rice. Total rice productivity on legumes-rice-rice rotation was much higher compared to that on rice-rice-rice rotation.The role of organic fertilizer on 3rd planting season can substitute NPK fertilizer, respectively 30 %, 28 % and 32% for improving the highest yield after twice of planting season.
